Question

question 1
a virus particle is a nonliving, microscopic agent composed of genetic material surrounded by a protein coat.
which facts accurately describe genetic material in viruses? select two correct answers.

a. genetic material in viruses is protected by a capsid.

b. genetic material within viruses is located in the nucleus.

c. viral genetic material attacks the host cells ribosomes.

d. genetic material in viruses can be composed of either dna or rna.

e. genetic material in viruses replicates through mitosis.

Explanation:

• Option a: The protein coat surrounding viral genetic material is called a capsid, which protects the genetic material. This is correct.
• Option b: Viruses are acellular and do not have a nucleus, so this is incorrect.
• Option c: Viral genetic material hijacks the host cell's machinery but does not specifically attack ribosomes directly; this is incorrect.
• Option d: Unlike cellular life, viruses can have either DNA or RNA as their genetic material, which is a key characteristic. This is correct.
• Option e: Mitosis is a cellular division process, and viruses use host cell machinery to replicate their genetic material, not mitosis. This is incorrect.

Answer:

a. Genetic material in viruses is protected by a capsid.
d. Genetic material in viruses can be composed of either DNA or RNA.
